Searle believes that consciousness "is a real part of the real world and it cannot be eliminated in favor of, or reduced to, something else" [1] whether that something else is a neurological state of the brain or a computer program. He contends, for example, that the software known as Deep Blue knows nothing about chess. He also believes that ...
Modern dictionary definitions of the word consciousness evolved over several centuries and reflect a range of seemingly related meanings, with some differences that have been controversial, such as the distinction between inward awareness and perception of the physical world, or the distinction between conscious and unconscious, or the notion ...
Consciousness is an ambiguous term. It can be used to mean self consciousness, awareness, the state of being awake, and so on.

The Astonishing Hypothesis is mostly concerned with establishing a basis for scientific study of consciousness; however, Crick places the study of consciousness within a larger social context. Human consciousness according to Crick is central to human existence and so scientists find themselves approaching topics traditionally left to ...
A science of consciousness must explain the exact relationship between subjective mental states and brain states, the nature of the relationship between the conscious mind and the electrochemical interactions in the body (mind–body problem). Progress in neuropsychology and neurophilosophy has come from focusing on the body rather than the mind.
Epiphenomenalism is a position in the philosophy of mind on the mind–body problem.It holds that subjective mental events are completely dependent for their existence on corresponding physical and biochemical events within the human body, but do not themselves influence physical events.
According to philosophical materialism, mind and consciousness are caused by physical processes, such as the neurochemistry of the human brain and nervous system, without which they cannot exist. Materialism directly contrasts with monistic idealism, according to which consciousness is the fundamental substance of nature.
